Zusammenfassung:	53 A dual threshold is used in a coherent phase shift keyed demodulator to distinguish situations in which an incoming carrier signal is expected from those open ended conditions when a receiver is active, but when an incoming signal is not imminently expected. The use of a lower threshold permits more rapid detection and demodulation of a valid carrier signal by utilizing a standard which is less strict to determine the presence of a valid carrier signal when an incoming carrier signal is expected.
